just a quick question, when I click on the forge download link it takes me to the forge website and it has a bunch of different 7.7.0.500, such as 7.7.0.591, 7.7.0.590, 7.7.0.589 files and I was just wandering which one I should use.
The version that you require depends on the version of Minecraft you are using.
For 1.5.0 : Forge V7.7.0
For 1.4.7 : Forge V6.6.0
For 1.4.6: Forge V6.5.0
For 1.4.5: Forge V6.4.0
Those are the major releases found on the MinecraftForge.net Forums
I hope that helps, If you need further help post below with more information and i can guide you further
yeah i have forge 7.7.0 but there are subfiles on the forge website such as 7.7.0.591 or 7.7.0.590 ect. i used 7.7.0.591, the latest universal build, and it made my minecraft have a black screen, so i forced update for a new minecraft.jar file
